比色测定铝合金中微量锌的方法很多。利用形成三元络合物比色测定铝合金中微量锌的方法也有所报导。但利用锌与1,10-菲萝啉-荧光桃红形成三元络合物比色测定铝合金中微量锌的方法还未见报导。锌与1,10-菲萝啉所形成的无色络阳离子能与荧光桃红形成红色的离子缔合物,借此进行铝合金中微量锌的比色测定。该法在水相中有较高的灵敏度,较好的准确性及重现性。通过有机溶剂萃取可
Colorimetric determination of trace amounts of zinc in aluminum alloy many ways. The use of the formation of ternary complex colorimetric determination of trace zinc in aluminum alloy has also been reported. However, the use of zinc and 1,10-phenanthroline - fluorescent pink ternary complex colorimetric determination of trace zinc in aluminum alloy has not been reported. Colorless cation formed by zinc and 1,10-phenanthroline can form red ion association with fluorescent pink, so as to carry out colorimetric determination of trace zinc in aluminum alloy. The method in the water phase has a higher sensitivity, better accuracy and reproducibility. Extract by organic solvent
